Description

These shims have been used by our dealers and installers to eliminate rear driveline vibrations. Zinc alloy construction for corrosion resistance.

These over-the-road heavy duty truck axle shims are a fast and accurate means to align front or rear axles of most popular tandem trailers and trucks. Specialty Products’ new Zinc Alloy shims offer another level of performance versus our traditional aluminum shims. For a small cost increase versus aluminum, you now have the hardness of our premium manganese bronze shims and a much improved compression strength as compared to aluminum shims.

Answered by the admin So the shims should be the same on either side, the thinner side of the
shim has to be pointing towards the front of the vehicle and the thicker
side towards the back of the vehicle.
The arrow points towards the front of the vehicle
